Justices of the Supreme Court of the United Kingdom are the judges of the Supreme Court of the United Kingdom other than the president and the deputy president. The Supreme Court is the highest court of the United Kingdom for civil and criminal matters in the jurisdictions of England and Wales and Northern Ireland. Judges are appointed by the King on the advice of the Prime Minister, who receives recommendations from a selection commission. The number of judges is set by s.23(2) Constitutional Reform Act 2005, which established the Court, but may be increased by the King through an Order in Council under s.23(3). There are currently 12 positions: one President, one Deputy President, and 10 Justices. Judges of the Court who are not already peers are granted the style Lord or Lady followed by a surname, territorial designation or a combination of both, for life. Qualification The Constitutional Reform Act 2005 sets out the conditions for the appointments of a President, Deputy President or Justice of the Court. That person must have held high judicial office (judge of the Supreme Court, English High Court or Court of Appeal, Northern Irish High Court or Court of Appeal, or Scottish Court of Session) for at least two years, or have held rights of audience at the higher courts of England, Scotland or Northern Ireland for at least fifteen years. This means it is not necessary for someone applying to become a judge of the Supreme Court to have previous judicial experience (allowing Jonathan Sumption QC, a leading barrister, to successfully apply for the role in 2011). Appointment Judges of the Supreme Court are appointed by The King by the issue of letters patent, on the advice of the Prime Minister, to whom a name is recommended by a special selection commission. The Prime Minister is required by the Constitutional Reform Act to recommend this name to the King and not permitted to nominate anyone else. Selection commission The selection commission is made up of the President of the Court, another senior UK judge (not a Supreme Court Justice), and a member each from the Judicial Appointments Commission, the Judicial Appointments Board for Scotland and the Northern Ireland Judicial Appointments Commission. By law, at least one of these cannot be a lawyer. Should the President's place on the commission be unfilled, that place is to be taken by the next most senior
